I have a 6950 with its shaders unlocked to 6970. In my tinkering I have noticed that the 6970 clocks, specifically memory, are too high for my particular card. The 6950 stocks at 800core/1250mem while the 6970 stocks 880core/1375mem. The memory used in the 6970 is rated at 1500, while the memory in the 6950 is rated right on spec at 1250. Mine seems to be stable at 1330 and I have been running at 1300. Here is where RBE comes into play: While I can adjust the 3D clocks with Afterburner, I cannot modify what the card jumps to when playing video - 500core/1375memory. Is it safe to use RBE to modify only the clocks? I was thinking of staying with the pattern and just modding those 500/1375 clocks to 500/1300.
